JWST-ERS 00:14:05.489 -30:21:04.64 2022-11-11 08:57:14.112 28.13 F444W-JWST PSN joust2022b We report on the detection of an infrared transient in JWST observations of Abell 2744. The candidate was discovered in NIRCam observations in Cycle 1 ERS Program 1324 (PI: Tommaso Treu) via image subtraction with an earlier epoch of the same program. The candidate was not detected in any filters in the template epoch, confirming the transient nature of the source. No host galaxy can be attributed to the source. The first epoch was taken on MJD 59759, and the second epoch was taken on MJD 59894, a separation of 135 days. We report AB magnitudes for the target by performing simple aperture photometry, and the measurements are relative to current JWST photometric calibration estimates. The source is detected in F277W, F356W, and F444W with magnitudes of 27.44 ± 0.04, 27.87 ± 0.06, and 28.13 ± 0.07 respectively. The limiting magnitude of the observation in these filters are determined to be ~28.5 mag at the 0.1 uncertainty level. The exposure times for these filters were 11144.764 (s), 16491.684 (s), and 65966.736 (s) respectively. The source is detected in F277W, F356W, and F444W.
